how often to change brita filter

You have had enough of your water not tasting as pure and clean as you would like it to be, and that slight odor that you get from it is outright embarrassing when you have guests over. You have thought about getting a Brita water filter, but how long do Brita water filters last?

Brita states that their standard filter or bottle filter should be replaced every 40 gallons or 2 months, Faucet Mount Filter every 100 gallons or 4 months, and their long last filter, every 120 gallons or 6 months. Excessive water contaminants may require changing your Brita filter more often.

Everyone wants to live a healthier lifestyle, and most people are willing to do things that will make them healthy and fitter (As long as it's easy to do). I think that this is why water filtering pitchers have become so popular. But water pitcher filters don't last forever.

How a Brita filter can improve your water, and for how long.

It is very important that you understand that passing your drinking water through an activated charcoal filter like the ones used in a Brita pitcher will only remove some of the impurities that can cause your water to have an unpleasant taste.

A Brita pitcher is not a reverse osmosis drinking water system .

Unlike a reverse osmosis drinking water system that uses a semi-permeable membrane for long term filtering of dissolved solids and other contaminants from your water, a Brita water filter removes contaminants from your water and has to be changed more frequently.

Excessive salts and other dissolved solids are not removed from your water, and using a Brita filtering pitcher does not ensure that you are drinking healthy water.

A Brita water filter is for the removal of Chlorine (Taste & Odor), Mercury, Cadmium, Benzene, Asbestos, Particulates, Copper, Zinc, and other contaminants that can add unpleasant taste or odor to your water.

How often do YOU need to change your Brita water pitcher filter?

I don't like to talk about how often you will need to change a Brita water filter without explaining that it's not as simple as X amount of gallons or X amount of time. It depends on the quality of the water to be treated and how much water is being used.

You may use more or less water than your next-door neighbor, and your friend down the road may have very different water issues than you do. So naturally, you may need to change your Brita water filter more or less often than they will.

Brita states that their standard filter should be changed after 40 gallons of water have gone through it, or 2 months, whichever comes first.

How to gauge how often you should change your Brita filter.

Since Brita has a few different sized containers, I recommend that you figure out how much water you use per day to calculate how often the filter should be changed.

I recommend determining filter changes by days or weeks rather than by container fill-ups because if someone has a tendency to fill the container, and does not log in that they did, then you could be using the filter way longer than you should.

Pay close attention to your filtered water usage for 1 week, and then you should be able to determine very closely, how soon that you will use 40 gallons of filtered water.

For example, if you find that you use 10 gallons of Brita filtered water in one week, you should change your standard Brita water filter after 4 weeks. If you find that you only use 5 gallons in one week, then you should change your standard Brita water filter every 8 weeks.

It's up to you how strict you want to adhere to the 40-gallon change rule, I don't like to call it a rule, but rather just a rule of thumb.

Brita recommends a new filter every 40 gallons of water used based on what they expect to be an average case scenario of water that a Brita water filter would be effective for. If your water tastes horrible straight from the tap, you should probably be changing your filter cartridge every 40 gallons (or sooner).

How long will a Brita filter remove chlorine?

Chlorine in municipal water is one of the leading reasons why people choose to use a Brita water filter. Chlorine gives water an unpleasant taste, and odor making it less desirable to drink.

Because the level of Chlorine in municipal water can vary from household to household. If your water has a high level of Chlorine in it, your Brita water filter may not last as long as with water with a lower level of chlorine in it.

A Brita water filter uses carbon to remove chlorine from your water, but the carbon is not effective forever and high levels of chlorine can shorten the effective life of the carbon in a Brita water filter.

How chlorine may affect how long your Brita water filter will last.

The approximate life expectancy of a Brita water filter for chlorine removal.

Level of chlorine in Parts Per Million	Standard Filter	Long Last Filter	Bottle Filter	Faucet Filter
0 – .5	40 Gallons or 2 Months	120 Gallons or 6 Months	40 Gallons or 2 Months	100 Gallons or 4 Months
.6 – 1.0	30 Gallons or 6 Weeks	100 Gallons or 5 Months	30 Gallons or 6 Weeks	80 Gallons or 3 Months
1.1 – 1.5	20 Gallons or 1 Month	60 Gallons or 3 Months	15 Gallons or 3 Weeks	50 Gallons or 2 Months
1.6 – 2.0	10 Gallons or 2 Weeks	20 Gallons or 1 Month	10 Gallons or 2 Weeks	25 Gallons or 1 Month

If your water is very poor tasting to start with, you should consider a reverse osmosis drinking water system for a much higher level of water purification.

But if you are using your Brita filtering pitcher just as a precautionary measure to make you feel a bit better about the water that you are drinking, then you may only want to change the carbon cartridge every 50 gallons or so since they are a bit expensive.

What your Brita filter does, and why you need to change it.

If you are using your filter for water that needs minimal filtering, the filter should be able to last longer than if you are filtering highly contaminated water. This should be true, but is it?

A Brita filter cartridge (both white and blue) uses activated carbon to remove certain contaminants in water that can give it a metallic, chemical, or other odd taste. This activated carbon loses its ability to remove contaminants the more that it is used.

This means that the activated carbon in a Brita filter will lose its effectiveness at some point, whether the water being treated is full of contaminants or not.

What happens if you don't change your Brita filter often enough?

Even if the Brita water filter is no longer effective at removing contaminants from your water, it does not mean that the filter is not affecting your water at all. A Brita water filter that is left in your water dispenser can be a breeding ground for bacteria.

The carbon used in a Brita water filter works great for removing contaminants from your water, but it also makes for a great place for bacteria to grow. Leaving a Brita water filter in your dispenser for too long may mean that it will develop bacteria and make your water worse rather than better.

The key point to take away from this is that a Brita filter that is removing high levels of copper from your water due to corrosion of the copper plumbing in your home may not last very long before your water will develop a metallic taste to it.

This is because the filter can quickly become saturated with the copper particles which are larger than most of the other particles that a Brita water filter is designed to remove.

A Brita filter does not actually work as a standard water filter!

It is important to understand that an activated carbon filter cartridge like the ones used in a Brita pitcher is not a filter at all.

A filter captures a substance from going through it. But an activated carbon cartridge allows the water to flow over the carbon while trapping some of the metals and chemicals contained in the water in its pores.

Because activated carbon does not completely remove all the contaminants that can cause unpleasant tastes in your water, if you have high levels of metals, salt, or chemicals, you will be much better off using a reverse osmosis drinking water system to purify your drinking water.

I found this highly rated and recommended Reverse Osmosis system at a great price. It is a very effective way to make your water better for you and your family.

How to change your Brita filter.

The original Brita filter cartridges required pre-soaking before installing, so if you are still using the original style filters, pre-soak the filter in clean cold water as directed on the filter packaging.

Start by washing your hands thoroughly, and have a few clean paper towels handy.

Clean your Brita filter pitcher or another type container well using non-abrasive dishwashing detergent and set it aside on a clean paper towel.

Fill a small bowl with enough cold water so it will completely cover the Brita filter once you place it in it. Carefully remove the filter from its packaging and place it in the bowl of water to soak for 15 seconds.

Remove the new filter from the water and let it drip for a few seconds. Align the filter to the filter housing so that the groove along the filter meets up with the notch inside the filter housing.

Note: One groove is a bit longer than the other so be sure to match them up correctly.

Keeping the filter as straight in-line with the housing as you can, insert the new filter in and press firmly for a tight fit. If you do not feel that the filter is in all the way, remove it from the housing, make sure it is aligned correctly and re-insert again.

The filter contains carbon which can have some carbon dust in it. This carbon dust may make the first few pitchers of water slightly cloudy. Discard or use the first 2-3 pitchers of water for something other than drinking (housecleaning, plants/flowers, etc.).

What should you do with your old Brita water filters?

When your Brita water filter is no longer effective, you should not simply throw them away!

Used Brita water filters should be sent back to Brita so they can be recycled by the Brita recycling program. Simply contact Brita filter recycling service, and they will instruct you on what filters can be recycled and how to send your used filters in for recycling.

Can you use Brita filters that have expired?

A Brita water filter comes in a sealed pouch that will keep your new filter fresh and usable indefinitely when stored in a cool and dry place.

However, an unused filter cartridge that has been removed from its sealed pouch should be soaked in clean water for 15 to 20 minutes before using it to ensure that the filter will be effective.

Although a Brita water filter that has been exposed to the air for a long period of time should work fine after soaking it for 15 to 20 minutes, it is possible that contaminants from the air could have settled inside of the filter.

If you are concerned that your opened but unused Brita water filter may not be safe to use, contact Brita customer service.

For most water, make sure to change your Brita filter every 40 gallons of use as directed by Brita if not sooner. At the current price of Brita filters, a gallon of Brita filtered water should average about 10 cents.

If you find your family requires more water than a filtering pitcher can provide and would rather have higher quality filtered water for around 3 cents per gallon, you may want to consider a reverse osmosis drinking water system for plenty of pure water without having to always be re-filling a pitcher.
